Specification of Letters Patent.

Patented July "7 1914..

Application filed February 17, 1914. Serial N 0. 819,264.

To all whom it may concern Be it known that I, CASPER FAUs'r, a citizen of the United States, and resident of. ()Slll-IOSll, in the county of Winnelmgo and State of Wisconsin, have invented certain new and useful Improvements in Bridge Gates; and I do hereby declare that the :t'ollowing' is a full, clear, and exact description thereof.

My invention refers to swinging bridges, its object being to provide a simple, eco nomical and effective set of guard-gates therefor, the arrangement, and construction being such that the diametrically opposite gates are connected in pairs, whereby incoming gates from both approaches are simultzmeously closed followed by closure 01 the outgoing gates.

One of the particular objects of my present invention is to provide a gatenctuating mechanism all connected above ground, whereby economy in insulation is el'lccted due to the fact that it is not necessary to excavate under the abut-merits for installation.

With the above and other objects in view the invention consists in certain peculiarities of construction and combination of parts set forth hereinafter with reference to the accompanying drawings and sub scqucntly claimed.

in the drawings Figure 1 represents a plan view of a horizontally swinging bridge and its abntments equipped with gates embodying the features of my invention, parts being broken away and in section to more clearly illustrate details of co1l struction; Fig. 9, a longitudinal sectional view of the same, the section being indicated by line 2 2 oil. Fig. 1; Fig. 3, a detailed ci-osssection ot' the bridge showing the gate-actuating mechanism attached thereto, the section being indicated by line 33 of Fig. 1, and Fig. i, a detailed crosssection through the abutment, showing one of the guard gates and its connected actuating rod, the section being indicated by line 4.- l of Fig. 1.

Referring by characters to the drawings, 1, 1., represent the abutments of a horizontally swinging bridge 2 of any desired con struction. Each abutment is provided with a pair of pillars 3 at points intersecting the walk and street line or curb. These pillars have mounted therein the posts t of sidewalk and roadway gates 5, preferably of the specific form of rent to the edge of the abutment bearings that depend from the lower lattice-work type. Alined with the curbing of each abutment in juxtaposed posh tion to the pillars are a pair of guide-blocks (5 carrying anti-friction rollers, bet-ween which is slidably mounted sections of gate actuating rods 7, 7', the same being pro vided with squared sections which engage the slide-blocks to thus prevent the rods from twisting in their seats. The abutment rod sections are connected to the gates by links 8, the fulcrum points of which linlts are so arranged that when the gates are closed they form locks to prevent movement thereof in either direction exceptthrough a positive movement imparted to the actuating rods. Thus the gates are antomatically locked in their closed position, in which position they extend across both th roadway and sidewalk.

\Vhile I have shown and described one gate, it is obvious that I may, without departing From the spirit of my ii'ivention, gear connect the actuating rods to any type of gate.

The ends f the rod sections 7, 7, adjaare provided with coupling members 9, 9, 9, 9, respwtively. These coupling members are in the form of upwardly projecting J-sha ped heads which are adapted to interlock with corresponding downturned couplii mem' bers 10, 10, 10, 1.0, which are carried at the ends 0t gate-actuating rod-sections 11, 1.1, 171., 11. The last mentioned series of rod sections are slidably mounted, in blocks 12, which blocks are carried by the liiridge. llence each gate-actuating rod is composed of two sections one o'l which is carried by the abutment and the other alined section is mounted upon the swinging bridge.

The inner ends of the lnridge-carried rodsections 11 are disposed upon diametrically opposite sides of the bridge and are connech ed by a transversely disposed roc shaft 13, which rock-shaft is suitably journaled in I side of the bridge, as shown. The ends of the rockshaft 13 are provided with lever-arms 14:, l t, the lever-arm 14, being in pin and slot connection with the innercnd of one of the gate-actuating rod sections 11, while the op posite lever 1 1" is connected by a link 15 to the down'uuirdly extended leg 15 of the opposite rod section 11, the said leg being adapted to play within a slot 15 that is formed in the bridge floor. Thus it is obvious that the diametrically oppositely disposed gates are connected and actuated simultaneously. The gate-actuating means comprises a stud-shaft 16 that is journaled in a bearing with which the overhead structure of the bridge is provided. The studshaft has secured thereto a lever-arm 17, which lever-arm is in pin and slot connection with that gate-actuating rod-section 11 having the downwardly extended leg 15. The stud-shaft carries a gear-wheel 18, which gear-wheel is adapted to be thrown into clutch with a motor A by means of manual shift of a clutch-plate 19, which clutch-plate carries a gear element that is adapted to transmit motion from the motor to said stud-shaft. The diametrically opposite set of gates, which are connected to the abutmentactuating rod section 7, are actuated by mechanism similar in construction to that just described, the bridge-carried actuating rod sections 11, being similar to that previously mentioned. These rodsections are connected by a suitable lever mechanism to a rock-sha t 21, which rock-shaft is similar in every respect to that previously described. The second set of actuating rod sections 11 are operated by a stud-shaft 16 carrying mechanism similar to that previously described, the gear of which shaft is adapted to be connected to the motor through shift of the clutch-plate.

By this arrangement the. motor and actuating mechanism for the two sets of gates is all arranged at the positions centrally of the bridge and to one side thereof, whereby it may be conveniently controlled by a single operator, but itis understood that I may, without departing from the spirit of my invention, operate each connected set of gates from opposite sides of the bridge, if desired. It is also manifest that, while I have shown and described the incoming and outgoing gates as being under control of a motor, I may, without departing from the spirit of my invention, utilize a hand power mechanism of any desired type, the essential element being that the incoming gates are operated siimiltaneously, succeeded by a simultaneous operation of the outgoing gates to thus insure clearing of the bridge and avoidance of accidents. lit is also within the scope of my invention to utilize a single set of the diagonally arranged gates, in which instance the said gates would be of a length to extend entirely across a comparatively narrow roadway, but, under all conditions the actuating mechanism for operating the gates would be arranged above the surface to eliminate cost of installation.

I claim:

1. The combination of a swinging bridge with its abutments, and a swinging guard gate mounted above each abutment upon diametrically opposite sides thereof, a longitudinally disposed slidable actuating rod section in operative connection with each gate, each of said rods being mounted above its corresponding abutment, a coupling member carried at the opposite end of each rod section, a pair of rod-sections slidably mounted upon the bridge at opposite sides thereof and extending in opposite directions, coupling members carried at the outer ends of the same for engagement with tie cou pling members of the abutment gate-actuating rod sections, a transversely disposed rock-shaft carried by the bridge and mounted thereunder, lever mechanism connecting the rock-shaft and each gate-actuating rod section of the bridge, and actuating mechanism for said bridge rod sections.

2. The combination of a swinging bridge with its abutments, and a pair of swinging gates mounted upon each abutment, a longitudinally disposed slidable actuating rod section in link connection with each gate, coupling members carried at the free ends of each rod. section, slidable rod sections mounted upon the bridge each adapted to be alined with a companion abutment actuating rod, a coupling member at the outer end of each of the bridge rod sections for engagement with the corresponding member of its companion abutment rod section, a pair of rock-shafts arranged transversely of the bridge, lever mechanism connecting each rock-shaft with the diametrically opposite bridge-carried rod-sections, and means for actuating the shaft-connected actuating rods independently.

In testimony that I claim the foregoing I have hereunto set my hand at Milwaukee in the county of lllilwaukee and State of l Viscousin in the presence of two witnesses.
